Narrow Space Thermal Management / IC Cooling - Small DC Blower Fan Motor #ThermalManagement
BF Series (BF1804 to BF8020)
Localized heat dissipation due to the electronicization of machinery. A compact blower fan that achieves reliable cooling with high static pressure and high negative pressure. Supports small lot production starting from several dozen units.
In the current era, where the automation of industrial equipment and the transition from mechanical control to electronic control are rapidly advancing, "thermal management" within equipment has become an extremely important issue. Particularly in environments where heat sources such as ICs, circuit boards, and transmissions are densely packed in confined spaces, reliable heat dissipation is essential to prevent thermal runaway and system downtime. In general axial fans, there may not be enough static pressure to push air through the many obstacles inside the equipment, resulting in insufficient cooling effectiveness. This is where our "compact DC blower fan motor" comes into play, capable of ensuring airflow and high negative pressure and static pressure. It effectively bends the airflow at a right angle and blows it out forcefully, demonstrating tremendous power for pinpoint cooling in high-resistance flow paths and limited spaces. At Crew Co., Ltd., we leverage the cost advantages of overseas ODM while delivering the peace of mind of Japanese quality through thorough inspection of all units domestically. We also cater to small lot needs, such as "I want several dozen units for prototyping first."

basic information
■Characteristics of Blower Fan Motors (Differences from Axial Fans) By utilizing centrifugal force to expel air, they generate higher static pressure (pushing and sucking force) compared to axial fans. They are optimal for localized cooling and heat dissipation in equipment with densely packed components and high air resistance. ■Kuru's Small DC Blower Fan Motors - Product Lineup: A wide range of small DC blower fan motors is available. - Lot Support: Capable of accommodating small lots of several dozen units. - Quality Assurance System: Our company absorbs the risks of direct imports from overseas. Thorough domestic inspections are conducted for all units, from small lots to mass production. - Technical Support: Dedicated domestic staff will assist until technical challenges are resolved, including remote support and on-site visits.
Price information
We provide overwhelming price competitiveness by leveraging our unique global procurement network (world-class ODM products) to significantly reduce development and implementation costs. Breaking the common belief that "mass production starts from thousands of units," we offer price advantages equivalent to mass production even for small-scale starts with dozens of units, minimizing initial investment and inventory risks for companies.
